固定相：专用

规格：1m*1/8

型号：HH-Benzene series

应用：空气中苯系物测定

滕州市浩瀚色谱仪器技术服务有限公司，研发一种测定固定污染源废气中苯系物成分含量的方法，步骤如下：气相色谱分离，被测样气导入进样器中；氮气经减压阀调整压力后通过气体纯化器去除水分、烃与氧等杂质；经精细压力调整后进入进样器；样气被送色谱柱进行分离；差分光谱吸收，样气经色谱柱分离后导入检测室；使用紫外光源与红外光源组成的联合光源穿过检测室，以光谱仪检测样气的吸收光谱；计算得到苯系物成分含量。本发明能够快速连续地对固定污染源废气中苯系物进行分析，克服了常规气相色谱技术定性能力差；且可大大缩短苯系物的分析周期，将分析周期由常规色谱法的30分钟以上缩短到5分钟以内，并可进行连续检测与检测因子扩展。

On-line dedicated column for benzene series of fixed pollution source exhaust gas
Special online column for benzene series of fixed source exhaust gas Details:

Stationary phase: dedicated
Specification: 1m * 1/8

Model: HH-Benzene series

Application: Determination of benzene in air

Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. has developed a method for determining the content of benzene compounds in the exhaust gas from a fixed pollution source. The steps are as follows: gas chromatography separation, the measured sample gas is introduced into the sampler; nitrogen pressure is adjusted by the pressure reducing valve Then remove impurities such as moisture, hydrocarbons and oxygen through a gas purifier; enter the sampler after fine pressure adjustment; the sample gas is sent to the chromatographic column for separation; differential spectral absorption, the sample gas is separated into the chromatographic column and introduced into the detection chamber; used A combined light source composed of an ultraviolet light source and an infrared light source passes through the detection chamber, and the absorption spectrum of the sample gas is detected by a spectrometer; the content of the benzene series component is calculated. The invention can quickly and continuously analyze benzene compounds in the exhaust gas from a fixed pollution source, overcomes the poor qualitative ability of conventional gas chromatography technology, and can greatly shorten the analysis cycle of benzene compounds, shortening the analysis cycle from more than 30 minutes by conventional chromatography. Within 5 minutes, continuous detection and detection factor expansion can be performed.
